CENTRIFUGAL GOVERNOR.

SPECIFICATION forming part of Letters Patent No.

To all whom it may concern:

lie it known that I, EUcENE MATHIEIT, a citizen of the Republic of France, residing at Louvain, in the Kingdom of Belgium, have invented certain new and useful Improvements in Centrifugal tnrovernors, of which the following is a specification.

This invention relates to centrifugal governors, such as are used in combination with explosion-engines, and has for its purpose to secure an apparatus of this kind which will be adapted to operate with an exceptionallygrcat sensibility and without any objectionable friction.

\Vith this object in view my invention cs sentially consists in the combination of two disks or washers and of balls located between said disks or washers, one of said disks being adapted to rotate, while the second disk or washer is adapted to be displaced under the action of the centrifugal force developed in the balls rotating with the first disk or washer, the movement of said second disk or washer being used as a means for actuating a clackvalve or any other appropriate controiling device suitably mounted in the gas or mixture inlet pipe of the engine or motor.

In carrying the invention into practice the disks or washers fmrming part of the governor may be suitably shaped and provided with straight or curved or inclined surfaces adapted to vary the action which opposed through said washers to the action of the centrifugal force, so as to counterbalance the centrifugal action in a very short time or in any given or predetermined conditions.

The annexed drawings show, Figures 1 and 2, a vertical section of a centrifugal governor, l ig. 1, (.(Hlfiid'ilt'ttdl according to my invention, the said governorbeing combined with the clack-valve, Fig. 1, of an explosionmotor.

In the drawings, 1 is the driving-shaft of the motor, actuating through a pinion 2 washer or disk I provided with a toothed periphery 3", the teeth of which engage with the teeth of pinion The washer 3 turns loosely on an auxiliary shaft 4; or may be keyed upon said shaft, which may be used as a cam-shaft for the distrilmtion of the upon said shaft and to act during said dis- 6o placement on a forked lever 9, rocking upon an axle 10, supported by the casing 11 of the governor in a suitable bearing, and fitted outside of the casing 11 with an arm 1;, adapted to be connected through a chain 13 or through any suitable connection with a clack-valve l5, interposed in the air or gas or mixture pipe 16, according to the mode of regulation of the engine.

The washer S is held in the position shown on the drawings by aid of a spring 1 7, having one end connected to the arm 12 and its second end connected to a fixed point outside of the casing 11.

The governor thus constructed acts in the following manner: The engine being in optl'tttitlll, the driving-shaft 1 rotates washer 3 by aid of the pinion i and of the toothed periphery E3. The balls 7 are carried alongby the washer 3, and owing to the action of the centrifugal force tend to rise along theincline 18 of t he recesses 6 and to force back the washer or disk 8 against which they are thrown. As a result of this, simultaneously as the said balls rotate with washer 3 they are rotated in the recesses 6 and cannot produce any objectionable friction or jamming. ()wing to the longitudinal d isplacement of washer h upon the shaft 4, the forked lever I) is oscillated and acts through arm 12 and chain 13 on the clack-valve 15, which, as shown in dotted lines, closes more or less (according to the action of the governor) the section of the pipe lo, through which the gas or explosive mixture may accede to the inlet-valve of the moron It will be easily understood that owing to the special combination of the parts or elements of the governor, hercinbefore deseri I led, the conditions of operation of thegovernor may be ealeulat ed very easily and without any spoeial ditiieulty. The curved or inelined surface to of the reeesses ii in washer i, and the eurved or inelined surface oi washerhwhieh both act upon the halls in eonjunetion with the action otthe spring 17 in order to eounterbalanee the aetion ol'the eentrit'ugal loree, may be so shaped as to give to the governor a very great sensibility only between two given speeds of revolution of the driving-shaft 1, and it will be understood that I do not eontine myself to the exaet form or shape of the disks or washers shown in the drawings, said details varying neeessarily with tho speeial eonditions of operation ot eaeh governor.

What I elaim is- I. In a centrifugal governor, the eombination with a driving-slutl't ot' a washer rotated by said shal't, balls earried along in the rotation of said washer, a seeond sher shaped so as to counterbalanee the aet ion of the eontrit'ugal foree generated in the balls and adapted to bedisplaeed longitudinally bythe balls and means for transmitting the movements of said washer, substantially as de seribed.

2. In a centrifugal governor the eombination with a driving-shaft ot' a washerrotated by said shal't said washer being provided with a number of reeesses, a ball in eaeh of said reeesses, a seeond washer mounted. loosely on the shaft and ntaintainingtluballs in the said recesses, the said seeond washer being adapted to be displaeed longit udinallyonthe shat't through the balls when they are displaeed in their reeesses under the aetion ot' the eentritugal t'oree and meanstransmitt ing l neetions eonnt'a'ted with said eap,

the movement of the said washer, substantially as deseribt'id.

23. In a ('entrit ugal. governor the eombination with a drivin -shat't of a washer rotated by said shal't, said washer being provided with a number of recesses, a ball in eaeh of said reeesses,a seet md washer mounted loosely on the shaft; and adapted to balls in their reeesses, the said seeond washer being adapted to be displaced longitudinally on the shaft through the halls when they are displaced in their recesses under the aetion ot' the eentritugal t'oree, a spring aeting on said seeond washer, a forked lever on which the seeond washer aets when displaeed longitudinally an axle on wbieh said lever may be oseillated and an arm for transmitting the i movement ot the seeond arm to the part to be operated by the governor, substantially as deseribed and for the purpose set forth.

4. In combination the motorshal't having a gear thereon, a second gear meshingthere with and having ball-reeeiving poekets in its t'aee with inelined outer walls, balls seated in said poekets, a retaining eap or washer mounted to rotate in proximity to said gear and having an inelined outer tlange overlapping the balls, said eap being movable toward and from the gear, and speed-eontrolling eonsubstan tially as deseribed.
